Abstract

The present disclosure provides an information processing apparatus including, a detection unit configured to detect the position of an operating body relative to a display surface of a display unit displaying an object group made up of a plurality of objects each being related to a content, and a display change portion configured to change a focus position of the objects making up the object group based on a result of the detection performed by the detection unit, wherein if the result of the detection by the detection unit has detected the operating body moving linearly in a predetermined operating direction thereof substantially parallel to the display surface, then the display change portion changes the focus position of the objects spread out circularly to make up the object group, in a manner moving the focus position in the spread-out direction.

1 . An information processing apparatus comprising:
 a detection unit configured to detect the position of an operating body relative to a display surface of a display unit displaying an object group made up of a plurality of objects each being related to a content; and   a display change portion configured to change a focus position of said objects making up said object group based on a result of the detection performed by said detection unit; wherein   based on the result of the detection, if said detection unit has detected said operating body moving linearly in a predetermined operating direction thereof substantially parallel to said display surface, then said display change portion changes the focus position of said objects spread out circularly to make up said object group, in a manner moving said focus position in the spread-out direction.   
     
     
         2 . The information processing apparatus according to  claim 1 , wherein said display change portion changes the format in which said object group is displayed based on a proximate distance between said display surface and said operating body, said proximate distance being acquired from the result of the detection performed by said detection unit. 
     
     
         3 . The information processing apparatus according to  claim 1 , wherein, based on the result of the detection, if said detection unit has detected said operating body moving in a direction substantially perpendicular to said predetermined operating direction, then said display change portion determines to select the content related to the currently focused object. 
     
     
         4 . The information processing apparatus according to  claim 1 , wherein said display change portion changes the focus position of said objects making up said object group in accordance with the amount by which said operating body has moved relative to said display surface. 
     
     
         5 . The information processing apparatus according to  claim 1 , wherein said object group is furnished with a determination region including said objects; wherein
 said determination region is divided into as many sub-regions as the number of said objects included in said object group, said sub-regions corresponding individually to said objects; and   said display change portion focuses on the object corresponding to the sub-object on which said operating body is detected to be positioned based on the result of the detection performed by said detection unit.   
     
     
         6 . The information processing apparatus according to  claim 5 , wherein said display change portion changes said determination region in such a manner as to include said content group in accordance with how said content group is spread out. 
     
     
         7 . The information processing apparatus according to  claim 5 , wherein, if said operating body is detected to have moved out of said determination region based on the result of the determination performed by said detection unit, then said display change portion displays in aggregate fashion said objects making up said object group. 
     
     
         8 . The information processing apparatus according to  claim 1 , wherein said display change portion highlights the currently focused object. 
     
     
         9 . The information processing apparatus according to  claim 1 , wherein said display change portion displays the currently focused object close to the tip of said operating body. 
     
     
         10 . The information processing apparatus according to  claim 1 , wherein, if an operation input is not detected for longer than a predetermined time period based on the result of the detection performed by said detection unit, then said display change portion stops changing the focus position of said objects making up said object group. 
     
     
         11 . An information processing method comprising:
 causing a detection unit to detect the position of an operating body relative to a display surface of a display unit displaying an object group made up of a plurality of objects each being related to a content;   causing a display change portion to change a focus position of said objects making up said object group based on a result of the detection performed by said detection unit; and   based on the result of the detection, if said detection unit has detected said operating body moving linearly in a predetermined operating direction thereof substantially parallel to said display surface, then causing said display change portion to change the focus position of said objects spread out circularly to make up said object group, in a manner moving said focus position in the spread-out direction.   
     
     
         12 . A computer program for causing a computer to function as an information processing apparatus comprising:
 a detection unit configured to detect the position of an operating body relative to a display surface of a display unit displaying an object group made up of a plurality of objects each being related to a content; and   a display change portion configured to change a focus position of said objects making up said object group based on a result of the detection performed by said detection unit; wherein   based on the result of the detection, if said detection unit has detected said operating body moving linearly in a predetermined operating direction thereof substantially parallel to said display surface, then said display change portion changes the focus position of said objects spread out circularly to make up said object group, in a manner moving said focus position in the spread-out direction.
